High-order aberration correction for optimization of human visual function
View Patent ↗The present invention relates to the optimization of human visual function by correcting and/or optimizing high-order optical aberrations in high performance optical devices. The optimization is particularly useful for high performance devices used under low light conditions such as binoculars, rifle scopes, telescopes, microscopes, night vision goggles and laser eye protection devices.
1. A method of manufacturing an optical element, the optical element improving contrast sensitivity, low-contrast visual acuity, and vernier acuity in one eye of a subject, the method comprising:
obtaining a prescription for the one eye, wherein the prescription comprises corrections for one or more high order aberrations in the subject's one eye, wherein the prescription further comprises an aberration structure inside a 3 mm diameter of an optical center of the lens, wherein the aberration structure is selected to maximize a modulation transfer function (MTF) below a Nyquist resolution of the subject's one or more eyes, wherein a Nyquist resolution limit is a minimum visual acuity measured due to a cone density in a human fovea; and
applying the prescription to the optical element, wherein the optical element is configured for use as a eyepiece of one or more of a telescope, a microscope, a rifle scope, a binoculars and a spectacle lens and further comprises a cured polymer, the cured polymer material comprising a fixed index of refraction, and wherein the one or more high order aberrations are symmetrical high order aberrations.
2. The method of claim 1 , further comprising eliminating or modifying the one or more high order aberrations to produce an optimal visual acuity and contrast sensitivity.
3. The method of claim 1 , wherein the optical element further comprises a three-layered structure, wherein a center layer of the three-layered structure comprises a sandwiched cured polymer material that has a fixed index of refraction that corrects the one or more high-order aberrations, the method further comprising:
correcting one or more low order aberrations of two outer layers of the three-layered structure.
4. The method of claim 1 , wherein obtaining the prescription of the subject eye comprises receiving data collected by at least one selected from the group consisting of a wavefront aberrometer, an autorefractor, a phoropter, and a trial lens.
5. The method of claim 1 , further comprising correcting aberrations introduced during manufacturing before the one or more high order aberrations are corrected.
6. A method of manufacturing a spectacle lens, the spectacle lens improving contrast sensitivity, low-contrast visual acuity, and vernier acuity in one eye of a subject, the method comprising:
obtaining a prescription for the one eye, wherein the prescription comprises corrections for one or more high order aberrations in the subject's one eye, wherein the prescription further comprises an aberration structure inside a 3 mm diameter of an optical center of the lens, wherein the aberration structure is selected to maximize a modulation transfer function (MTF) below a Nyquist resolution of the subject's one or more eyes, wherein a Nyquist resolution limit is a minimum visual acuity measured due to a cone density in a human fovea; and
applying the prescription to the spectacle lens, wherein the spectacle lens comprises a cured polymer, the cured polymer material comprising a fixed index of refraction, wherein the one or more high order aberrations are symmetrical high order aberrations.
7. The method of claim 6 , further comprising eliminating or modifying the one or more high order aberrations to produce an optimal visual acuity and contrast sensitivity.
8. The method of claim 6 , wherein the spectacle lens further comprises a three-layered structure, wherein a center layer of the three-layered structure comprises a sandwiched cured polymer material that has a fixed index of refraction that corrects the one or more high-order aberrations, the method further comprising:
correcting one or more low order aberrations of two outer layers of the three-layered structure.
9. The method of claim 6 , wherein obtaining the prescription of the subject eye comprises receiving data collected by at least one of a wavefront aberrometer, an autorefractor, phoropter, or a trial lens.
10. The method of claim 6 , further comprising correcting aberrations introduced during manufacturing before the one or more high order aberrations.
11. A method of manufacturing an optical element, the optical element improving vision in one eye of a subject, the method comprising:
obtaining a prescription for the one eye, wherein the prescription comprises corrections for one or more high order aberrations in the subject's one eye, and
applying the prescription to the optical element, wherein the prescription further comprises an aberration structure inside a 3 mm diameter of an optical center of the lens, wherein the aberration structure is selected to maximize a modulation transfer function (MTF) below a Nyquist resolution of the subject's one or more eyes.
12. The method of claim 11 , wherein the Nyquist resolution limit is a minimum visual acuity measured due to a cone density in a human fovea.
13. The method of claim 11 , wherein the optical element is configured for use as a eyepiece of one or more of a telescope, a microscope, a rifle scope, a binoculars and a spectacle lens.
14. The method of claim 11 , further comprising eliminating or modifying the one or more high order aberrations to produce an optimal contrast sensitivity, low-contrast visual acuity, and vernier acuity.
15. The method of claim 11 , wherein the optical element comprises a cured polymer, the cured polymer material comprising a fixed index of refraction, and wherein the one or more high order aberrations are symmetrical high order aberrations.
16. The method of claim 11 , wherein the optical element further comprises a three-layered structure, wherein a center layer of the three-layered structure comprises a sandwiched cured polymer material that has a fixed index of refraction that corrects the one or more high-order aberrations, the method further comprising:
correcting one or more low order aberrations of two outer layers of the three-layered structure.
17. The method of claim 11 , wherein obtaining the prescription of the subject eye comprises receiving data collected by at least one selected from the group consisting of a wavefront aberrometer, an autorefractor, a phoropter, and a trial lens.
18. The method of claim 11 , further comprising correcting aberrations introduced during manufacturing of the optical element before the one or more high order aberrations are corrected.
